AC unit recommended repair by Cesar




Review of Mike Diamond Plumbing, Inc.

Cesar came out this morning and assessed my AC unit. He was very knowledgeable and explained in detail the issues I had with my AC unit. As soon as I can I will call to get the work done by Cesar. Thank you.


Cesar helped a lot




Review of Mike Diamond Plumbing, Inc.

Cesar unclogged my kitchen and laundry drain with a bigger cable that was cheaper than doing a hydroblast inside the drain pipe. I own a Pool company C52. My guys tried to unclogge it but cesar did it very. Happy we ll stick to pool services and stay away from residential plumbing
